BJU international·April 1, 2026·PMID: 41667130

What's New

A fixed-dose combination of dutasteride and tadalafil was associated with significantly greater symptom improvement than either drug alone in men with BPH.

Detailed Summary

A phase III randomized trial of 619 men with BPH found that a fixed-dose combination of dutasteride 0.5 mg/tadalafil 5 mg was associated with a 9.49-point reduction in IPSS at 48 weeks, compared to 4.40 for dutasteride alone and 4.24 for tadalafil alone (P < 0.001 for both). Adverse events occurred in 32.88% of the combination group vs 21.20% and 26.48% in the monotherapy groups.
